A833 rattles with new clutch and throw out

I have one that rattles a little bit in neutral with the clutch out. I'm guessing input bearing. It goes away as soon as the petal is pushed in. tmm

I would have to agree to a point, but it could be countershaft bearings.
The counter shaft spins in neutral with the clutch out, but the input shaft bearing is more common since the countershaft needle bearings are submerged in oil.
